Asymco’s Horace Dediu points out with the graph above that Apple has been adding about a million new store accounts every couple of days. The numbers seem to be based on Tim Cook’s announcement at WWDC that Apple now has 575,000,000 million store accounts (which we assume includes all App Store, iTunes, and Apple Online Store accounts). That means most of them have credit cards on file and as Cook noted, that’s “more accounts with credit cards than any other store on the internet.”
